Passengers could be caught up in lengthy delays and cancellations when workers at Southampton Airport go on strike.
The travel hub employees have announced a series of one-day strikes in a dispute over pay.
Members of union Unite including operations controllers, firefighters, technicians and engineering workers will walk out for 24 hours on November 5, 12 and 19.
Unite claims that some workers have not had a pay rise since 2019.
Taking the rates of inflation over the past three years into account, the means many of them are suffering a significant real terms pay cut.
A worker making £25,000 in 2019 should be on £28,697 today if they are to keep up with the rising cost of living, according to the Bank of England.
All three strike days fall on Saturdays, meaning potentially significant impact for people flying back from or to holiday destinations.
Unite general secretary Sharon Graham said: "During the pandemic workers at Southampton Airport made huge sacrifices, accepting reductions in pay and conditions while working around the clock to keep the airport safe and running.
"Inflation is now at a 40-year high. It's completely wrong for the employers, AGS, to refuse these safety critical workers a decent pay increase after a three-year freeze.
"The workers have had enough. The airport bosses need to make a realistic pay offer to the staff if they are to avoid an escalation of the dispute. They should do that now."
If the strikes are not averted with a revised offer to workers, then it will be the latest in a series of industrial action events affecting the travel network.
The RMT Union has been holding days of strike action since June over pay and job security.
Staff in ticket offices, stations, control rooms, and other support roles across Britain have been involved in the industrial action, often bringing rail lines to a standstill.
The unions latest strikes are planned for November 5, 7 and 9.
Airlines have managed to avoid workers striking in the UK, with a lengthy negotiation at Ryanair regarding cabin crew pay eventually being resolved earlier this month.
The same is not the case on Continental Europe, with Ryanair and easyJet staff in Spain walking out over the summer and early autumn.
A spokesperson for AGS Airports Ltd said: “We value our people and are determined to find a resolution. In an effort to do so we are engaging the dispute resolution service ACAS with a view to finding a way forward that works for all parties.”
